Eaton Crouse-Hinds CEX-133-B16-328PN - IECEx Zone 1
Part Number: CEX-133-B16-328PN
Quick Summary
Eaton Crouse-Hinds CEX cable mounted plug provides rugged power connections for hazardous-area machinery. Engineers struggle with unarmoured, gasketed IP68 solutions that fit tight spaces and meet hazardous-location codes. It carries IECEx/ATEX Zone 1 certification, IP68/IP66 ingress protection, and NEMA 6P 4X suitability for rugged, hazardous environments. As a result, it supports fast, compliant installation with Eex d glands and 16-shell configurations, delivering reliability, safer maintenance, and lower total cost of ownership. This makes it a strategic choice for panel builders, OEMs, and field engineers who demand robust hazardous-location connectors with durable copper contacts and proven sealing.

FAQs
The CEX-133-B16-328PN uses an EEx d gland designed for wiring unarmoured cables, which is essential for safe terminations in hazardous areas. It is Zone 1 certified under IECEx/ATEX, meaning equipment can operate in environments with explosive gas atmospheres. The gland provides a robust seal against dust, moisture, and chemical exposure, reducing ignition risk during field terminations.
It accepts #8 AWG conductors terminated by crimp contacts made of silver-plated copper, providing low contact resistance and high current capability. This combination is ideal for 55 A ratings and multi-pin assemblies, offering reliable, vibration-resistant connections in demanding hazardous-location environments.
Yes. The connector carries IP68 and IP66 protection ratings and is suitable for NEMA 6P 4X environments, enabling operation in wet, dusty, and harsh hazardous locations. The combination of sealing and rugged construction supports long service life with minimal maintenance in chemical plants, oil & gas facilities, and similar settings.
The connector features an 8.57 inch length, 2.25 inch width, and 2.25 inch height, housed in a 16-shell configuration. This compact footprint facilitates panel mounting in restricted spaces while maintaining compatibility with unarmoured cable assemblies and the EEx d gland for sealed terminations.
It meets IECEx/ATEX Zone 1 and NEC/CEC standards, along with IP68/IP66 and NEMA 6P 4X where applicable. This global certification suite enables use across regions without re-engineering, reducing regulatory risk, accelerating procurement, and supporting deployment in multinational projects requiring hazardous-location compliance.
